The guidance controller has detected the signal from the internal inertial sensor which measures lateral acceleration is outside of calibration limits.

 

The guidance controller uses inertial sensor to assist with guidance and improve accuracy on undulating terrain. The inertial sensors are inside the guidance controller and are unserviceable in the event of failure.

 

Failure Mode Indicator

FMI 13 – Out of calibration

 

Diagnosis and Solution

1 REPOWER THE GUIDANCE CONTROLLER.

a Disconnect power to the guidance controller via the appropriate switch for 30 seconds.

b Reconnect power to the guidance controller.

 

Expected Result:

Diagnostic fault code no longer exists.

 

Results:

• YES – The system reported a false diagnostic.

Repair: Report false diagnostic.

 

Proceed to step 2.

• NO – The guidance controller has a hardware failure.

Repair: The guidance controller requires replacement per customer’s warranty/replacement plan.

STOP.

 

2 REPORT FALSE DIAGNOSTIC

a Report the false diagnostic to AGCO Technical Support.

b Customer may resume operation of system.

c Ask customer to monitor system in case the error reappears.

STOP.
